24/7 AI answering service for HVAC companies

The HVAC answering service that books the job, not just the message

When a customer's AC dies at 9 p.m., they call the first company that picks up. InstantReply gives your HVAC business an AI receptionist that answers every call and text, books service calls straight into your schedule, and sends real emergencies to your on-call tech.

“We were missing leads because of slow replies, especially after hours. InstantReply fixed that by responding instantly, and we’ve seen more conversations actually turn into real opportunities.”

The customer with no AC calls three companies. The first one to answer gets the job.

In peak season your phone never stops. Your techs are on roofs and in attics, the office is one person juggling three lines, and after 5 p.m. everything goes to voicemail.

A homeowner sweating through a heat wave doesn't leave a message. They hang up and call the next company on Google. That missed call was a repair, maybe a maintenance plan, maybe a full system replacement five years from now.

You already paid for that call. The Google ads, the Local Services listing, the truck wrap. This is about answering the demand you've already bought.

A 24 hour HVAC answering service that works like part of your team

A traditional answering service takes a message and hands you a stack of callbacks. InstantReply is an AI receptionist for HVAC companies that handles the call all the way through. It works as three AI employees, and you can start with one.

AI Receptionist: answers every call and text

Picks up every inbound call and text, 24 hours a day. Asks the questions your CSR would ask: what's wrong, what kind of system, the address, and whether they're on a maintenance plan. Answers common questions like your service area, hours, and diagnostic fee. Books the call straight into your schedule. How fast lead follow-up works

What it doesn't do: diagnose problems or quote repair prices, other than the fixed fees you approve.

AI Follow-Up System: reaches new leads first

When someone fills in your website form or a Facebook lead ad, it calls them back in under 60 seconds and follows up by text. It sends appointment reminders 24 hours and 1 hour before, contacts no-shows to rebook, and follows up on replacement estimates that haven't been signed.

What it doesn't do: offer discounts or change prices you haven't approved.

AI Nurture and Close: fills your slow season

Reaches back out to past customers and old estimates sitting in your CRM, contacts customers due for a seasonal tune-up, and asks happy customers for a Google review after the job.

What it doesn't do: contact anyone who has opted out.

After-hours emergencies go to your on-call tech. Everything else waits for morning.

You decide what counts as an emergency. No heat when it's below freezing, no AC with an elderly person or a baby in the house, water leaking through the ceiling. When the AI hears one of those, it sends the call to your on-call tech with the address and details already collected.

If a caller mentions a gas smell or a carbon monoxide alarm, it tells them to leave the house and call the gas company or 911 first. Safety comes before booking.

Everything that isn't urgent gets booked for the next available slot. Your on-call tech stops getting woken up at 2 a.m. for a thermostat question.

Replacement estimates are where the money is. Most never get a second follow-up.

A homeowner gets three quotes for a new system and goes quiet. Your comfort advisor is out running the next appointment and doesn't get back to them for a week. By then, they've signed with whoever called back first.

Our AI Follow-Up System checks in on every open estimate, answers the easy questions, and books a second visit or a call with your advisor when the homeowner is ready to decide.

Old estimates from last season are worth working too. See how database reactivation works

HVAC answering service questions

What is an HVAC AI receptionist?

An AI that answers your calls and texts, asks the questions your CSR would ask, and books the job into your schedule. Unlike a traditional HVAC call answering service, it doesn’t just take a message for you to return later.

Will customers know they’re talking to AI?

It can tell them, and some states require it. Most homeowners with a broken AC care more about getting a tech booked fast than about who picked up.

How does it know what’s an emergency?

You tell us. We build your rules in, test them with you listening, and only go live once you’re happy with how it handles them.

Can it quote prices?

Only the fixed prices you approve, like your diagnostic or trip fee. It never guesses at repair or replacement costs.

Can we use it only after hours or when lines are busy?

Yes. You choose: after hours only, overflow when every line is busy, or every call.

Does it replace my CSR or dispatcher?

No. It picks up when your team can’t and handles the follow-up nobody has time for. Your team keeps the conversations that need a person.

Which software does it work with?

GoHighLevel as standard, with Jobber and Housecall Pro connected as an add-on.

How long does setup take?

Usually 5 days from kickoff to live.

How much does it cost?

It depends on which AI employees you need and your call volume. We give you an exact number on the demo.
